Why does Postobstructive diuresis occur?
Postobstructive diuresis is a polyuric response initiated by the kidneys after the relief of a substantial bladder outlet obstruction. In severe cases this condition can become pathologic, resulting in dehydration, electrolyte imbalances, and death if not adequately treated.
What is Postobstructive diuresis?
Postobstructive diuresis is a polyuric state in which copious amounts of salt and water are eliminated after the relief of a urinary tract obstruction. The incidence of POD is unclear but estimates suggest 0.5% to 52% of patients will experience POD after relief of obstruction.
How long does post ATN diuresis last?
Treatment of POD should be directed toward complete relief of urinary tract obstruction, replacement of electrolytes, correction of intravascular volume, and appropriate patient monitoring. The polyuric phase lasts about 48 hours, during which strict monitoring is necessary [18] .
What is Postobstructive pneumonia?
Postobstructive pneumonia is defined as an infection of lung parenchyma secondary to bronchial obstruction (4). It is often associated with lung malignancy (see Figure 1).
What is Anuric renal failure?
Anuria, sometimes called anuresis, refers to the lack of urine production. This can happen as a result of conditions like shock, severe blood loss and failure of your heart or kidneys. It can also be due to medications or toxins. Anuria is an emergency and can be life-threatening.
Is ATN reversible?
Acute tubular necrosis can last for a few days or as long as several weeks. For relatively healthy people, the condition can be reversible. For those with other health conditions, recovery may take longer and may not be complete.
What does Postobstructive mean?
What is Postobstructive pulmonary edema?
Postobstructive pulmonary edema (POPE; also known as negative pressure pulmonary edema) is a potentially life-threatening complication in which pulmonary edema occurs shortly after the relief of an upper airway obstruction.
What are the possible complications of post-obstructive diuresis?
Post-obstructive diuresis can cause serious consequences such as dehydration, electrolyte abnormalities, hypotension, hypovolemic shock, and even result in death.
What should patients pay attention to during postobstructive diuresis?
ReviewPostobstructive diuresis: pay close attention to urinary retention. [Can Fam Physician. 2015] ReviewPostobstructive diuresis: pay close attention to urinary retention.
What is the difference between postobstructive diuresis and high pressure hydronephrosis?
Prolonged high-pressure hydronephrosis can injure nephrons and result in renal dysfunction. 9 Box 1. Postobstructive diuresis is a polyuric state in which copious amounts of salt and water are eliminated after the relief of a urinary tract obstruction.
What is the prevalence of postobstructive diuresis in the US?
Postobstructive diuresis can occur in up to 50% of patients with substantial urinary tract obstruction and can be life-threatening if it becomes pathologic. Patients with decompressed urinary obstruction might have to be admitted for a 24-hour observation period.
